Heat Pump / Refrigeration. Can same overunity concept apply to Eletronics???

Thx a lot for the suggestion.

I think CO2 might be a good alternative to the water I'm going to use for the prototype.
All it would need is to keep the pressure in that circuit in a range that gives me a liquid in the normal outside temperatur range.
That should be possible.

I was also thinking about some alcohols before but dropped that because it's highly flameable.

CO2 is an oddity. It heats from Ice to Gas, Gas to Liquid, Liquid to Gas, Gas acting like Liquid and having floating Ice. Trans critical temperatures may best suit your purposes.
